I will apply knowledge from this chapter by accurately measuring temperatures in cooking, ensuring food safety. Additionally, I can monitor weather conditions and understand health indicators, such as fever, using thermometers effectively in everyday situations.
Tiwari Academy Discussion Latest Questions
To measure temperature with a laboratory thermometer, ensure it is clean and dry. Immerse the bulb in the substance, wait for the reading to stabilize, and read the temperature at eye level for accuracy.
Thermal equilibrium is the state in which two objects in contact no longer exchange heat because they have reached the same temperature.
Conduction is the transfer of heat through a solid material. It occurs when particles in the material collide, passing energy from the hotter to the cooler parts.
Thermal expansion is the increase in the volume of a substance when its temperature rises. This occurs because particles move faster and spread apart as they gain kinetic energy.
Absolute zero is the lowest possible temperature, 0 Kelvin or -273.15°C, where molecular motion theoretically ceases entirely. It is a fundamental concept in thermodynamics.
